Used as a coupling agent in hybrid organic-inorganic materials, this chemical enhances adhesion between polymers and inorganic surfaces such as glass, metals, and ceramics. It is particularly effective in sol-gel processes, where it helps form stable networks by reacting with both organic resins and silica precursors. Commonly applied in coatings, sealants, and composites to improve durability, moisture resistance, and mechanical strength. Also utilized in functionalizing surfaces for specialized sensors or catalysts due to its ability to anchor organic functional groups to siliceous supports.
